Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition which can correct the hue of skin while having a transparent feeling and can be beautifully finished, and which is excellent in feeling of use and has a bare skin feeling.

[0002]

2. Description of the Related Art Color pigments such as titanium oxide and iron oxide are incorporated in foundations. Since these coloring pigments have a high hiding power, when a cosmetic containing the same is applied to the skin, the hue of the skin is adjusted, and the skin can be made beautiful.

In conventional foundations, there has been a tendency to incorporate a large amount of these coloring pigments in order to cover, for example, skin spots and freckles. However, since the hiding power of the coloring pigment is due to scattering of light, if a large amount of the coloring pigment is blended, the finished product lacks transparency and a natural-looking natural finish cannot be obtained.

[0004] In recent years, women who are in their late teens to early twenties, in particular, have a preference for a bare skin finish, and there is a need for a cosmetic that can change the skin hue to obtain a beautiful, natural and bare skin finish. ing. In the case where no coloring pigment is added, there is no scattering of light from the coloring pigment, so that the transparency is increased but the hue of the skin cannot be changed. For the purpose of shielding ultraviolet rays, the particle size is 0.1 μm.
When the following inorganic ultrafine particles such as titanium oxide and zinc oxide, and extender pigments such as talc and mica are blended, there is a problem that whiteness becomes conspicuous due to scattering of these lights.

[0005]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a cosmetic composition having a sense of bare skin which can be beautifully and naturally finished by correcting the hue of the skin while having a transparent feeling, and which is excellent in usability. Is to do.

[0006]

Under these circumstances, the present inventors have conducted intensive studies and as a result, have found that a skin-colored cosmetic containing a specific proportion of a coloring pigment can correct the skin hue while having a sense of transparency. The present inventors have found that they can be finished beautifully and completed the present invention.

That is, according to the present invention, the color pigment is added in an amount of 0.5 to
4.0% by weight, and the appearance color is within a range of hue 5R to 10YR, lightness 3.0 to 8.5, and saturation 1.5 to 10.0 in the Munsell color system. To provide cosmetics.

After mixing, the surface of the color pigment can be easily treated by co-milling. Since the wet method hardly dissolves N-mono long-chain aliphatic acyl basic amino acids in water near neutrality and ordinary oil, calcium chloride is used as a solubilizing agent for N-mono long-chain aliphatic acyl basic amino acids. Is dissolved in an organic solvent, and then the color pigment is brought into contact with the color pigment, washed with water to remove calcium chloride, and dried to treat the surface of the color pigment. Alternatively, after dissolving the N-mono long-chain aliphatic acyl basic amino acid in acidic or alkaline water or an aqueous solvent and contacting the color pigment, the mixture is neutralized to near neutrality and the N-mono long The same surface treatment can be performed by depositing and attaching a chain aliphatic acyl basic amino acid, removing the salt generated by neutralization by washing with water, and drying (Japanese Patent Application Laid-Open (JP-A) Nos. 61-7202 and 61-720).
